In India we find a flora nearly allied to that which flourishes in tropical Africa, a soil which freely affords nourishment to both wild and cultivated plants, an irrigation either supplied directly by the monsoon rains or artificially conducted from the rivers. It is true that we travel for long distances, especially in north-western India, through true desert tracts, but other districts produce vegetation so dense and luxuriant that the air is filled with reeking, choking vapour as in a huge hothouse.
First there are bananas, the cucumber-shaped fruits which are the food of millions of human beings. From India and the Sunda Islands this beneficent tree has spread to Africa and the Mediterranean coasts, to Mexico and Central America. Its floury-white flesh, juicy and saccharine, fragrant and well-flavoured, is an excellent article of food. The large leaves of the banana are useful for various purposes—sunshades, roof thatch, etc.
When the hot season comes, how pleasant it is to dream in the shadow of the mango-tree! The tree is about sixty feet high, and the shadow beneath its bluish-grey leathery leaves is close and dense. The pulp of the fruit is golden yellow and juicy, rich in sugar and citric acid. It is difficult to describe the taste, for it is very peculiar; but it is certainly delicious.
From their home in China and Cochin China the orange and its smaller brother, the mandarin, have spread over India and far around. Amongst the many other fruits which abound in India are grapes, melons, apples and pears, walnuts and figs. Figs are green before they ripen, and then they turn yellow. The fig-tree is distributed over the whole world wherever the heat is sufficient. It is mentioned both in the Old and the New Testament. Under a kind of fig-tree Buddha acquired wisdom in the paths of religion, and therefore the tree is called Ficus religiosa. Nymphæa stellaris, the lotus flower, which, like the water-lily, floats on water, is another plant of great renown among Buddhists. The lotus is an emblem of their religion, as the Cross is of Christianity.
In India a large quantity of rice is cultivated. In the north-eastern angle of the Indian triangle, Bengal and Assam, in Burma, on the peninsula of Further India (the Malay Peninsula), as well as in the Deccan, the southern extremity of the triangle, rice cultivation is extensively developed. Wheat is grown in the north-west, and cotton in the inland parts of the country. The cotton bush has large yellow flowers, and when the fruit, which is as large as a walnut, opens, the inside shows a quantity of seeds closely covered with soft woolly hairs. The fruit capsules are plucked off and dried in the sun. The fibre is removed from the seeds by a machine, and is cleaned and packed in bales which are pressed together and confined by iron bands, and then the article is ready for shipping to the manufacturing towns, of which Manchester is the most important. In India and Arabia the cotton bush has been cultivated for more than 2000 years, and Alexander the Great introduced it into Greece. Now there are plantations all over the world, but nowhere has the cultivation reached such perfection as in the United States of America.
Crops which during recent decades have shown enormous development are those known as india-rubber and gutta-percha, so much being demanded by the bicycle and motor industries. In the year 1830, 230 tons of rubber were imported into Europe; in 1896, 315,500 tons. The demand became so great that a reckless and barbarous exploitation took place of the trees, the inspissated and dried sap of which is rubber, this tough resisting and elastic gum which renders such valuable services to man. In Borneo ten trees were felled for every kilogramme of gutta-percha. Now more prudent and sensible methods have been introduced. In Ceylon, Java, and the Malay Peninsula there are large plantations which make their owners rich men. In India the Brazilian tree (Hevea) is the most productive of all the rubber-yielding varieties. A cross cut is made in the trunk of the tree, and the milky juice runs out and is collected into receptacles. Then it is boiled, stirred, compressed, and spread on tinned plates, rolled up and sent in balls into the market. At present Brazil supplies two-thirds of all the rubber used.
Then we have all the various spices—cinnamon, which is the bark on the twigs of the cinnamon-tree; pepper, carried into Europe by Alexander; ginger, and cardamoms. There is sesamum, from the seeds of which a fine edible oil is pressed out, and then tea, coffee, and tobacco. A plant which is at once a blessing and a curse, and which is extensively cultivated in India, is the poppy. When the outer skin of the fruit capsule is slit with a knife, a milky juice oozes out which turns brown and coagulates in the air, and is called opium. The opium which Europe requires for medicinal purposes comes from Macedonia and Asia Minor. But the opium grown in Persia and India goes mostly to China, into which country it was introduced by the Tatars at the end of the seventeenth century. The Chinese smoke opium in specially-made pipes. A small pea of opium is pressed into the bowl of the pipe and held over the flame of a lamp. The smoke is inhaled in a couple of deep breaths. Another pellet is treated in the same way. Soon the opium-smoker falls into a trance full of dreams and beautiful visions. He forgets himself, his cares and his surroundings, and enjoys perfect bliss. He then sleeps soundly, but when he awakes the reality seems more gloomy and dreary than ever, and he suffers from excruciating headache. All he cares for is the opium pipe. Men who fall a victim to this vice are lost; they can only be cured when confined in homes. In Persia opium is usually smoked in secret dens, for there the habit is considered shameful, but in China both men and women smoke openly.
The sugar-cane is also grown over immense fields in India. The juice contains 20 per cent of sugar. In Sanscrit, the old language of India, it is called sakhara. The Arabs, who introduced it to the Mediterranean coasts, called it sukhar. And thus it is called, with slight modifications, in all the languages of Europe and many of those of Asia.
We must also not forget the countless palms which wave their crowns in the tepid winds of the monsoons. There are the date palms, the coconut palms, the sago palm, and a multitude of others. The sago palm, from the pith of which sago grains are prepared, is a remarkable plant. It flowers only once and then dies. This occurs at an age of twenty years at most.
The soil of India supports many kinds of useful trees—sandalwood, which is employed in the construction of the finer kinds of furniture; ebony, with its dark wood; the teak-tree, which grows to a height of 130 feet, and forms immense forests in both the Indian peninsulas and in the Sunda Islands. It is hard and strong, like oak, and nails do not rust in it. It is therefore used in shipbuilding, and also frequently in the inside of modern warships. The sleeping and refreshment carriages of railway trains are usually built of teak.
